Abstract

PURPOSE:To prevent the generation of air-hissing sound without spoiling beauty and visor functions. CONSTITUTION:Ranging from the upper position of the forward inclined part of a visor body 1 to the tip end (of the visor body 1), an angle of inclination of the visor body 1 with respect to a collar body 2 is gradually narrowed, so that, at the tip end, the collar body is integrated into one body toward the rear surface of the visor body 1. At the same time, a space 3 formed between the collar body 2 and the visor body 1 is closed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a visor body which is folded outward from the upper end edge of a collar body and extends continuously from the rear of the roof molding to the side mirror mounting portion on the side edge of the front window. The present invention relates to an automobile side visor that is installed.

[0002]

2. Description of the Related Art For vehicles, especially passengers, a rounded design has become mainstream instead of a box shape, and a roof molding has become extremely thin. Therefore, in order to match the side visor for automobiles to the vehicle of such a design, the eaves body 1 is integrally projected from the lower edge of the collar body 2 until then, and is mounted on the roof molding 6 including the upper side portion of the windshield. The side visor M (see FIG. 4) of the type described above is provided with an eaves body in a folded shape outward and downward from the upper edge of the collar body, and as shown in FIG. 5, the roof mall 6 and the side bottom end of the windshield are mounted in series. It is moving to a type of side visor M. In such an automobile side visor, the angle of the canopy body with respect to the collar body is uniform up to the front inclined tip portion, and at that tip portion, as shown in FIG. 6, the angle of the canopy body 1 with respect to the collar body 2 is large and the tip end is It has an open structure.

[0003]

The canopy body opens in an inverted V shape outward and downward from the upper edge of the collar body, and a triangular cross-section is provided between the collar body and the canopy body opened in the inverted V shape. An elongated space is formed. In addition, the mainstream of the rearview mirror has also changed from the fender to the type that is attached to the door, so that the pressure of the air flowing in from the opening at the tip is increased in the space during traveling, and resonance occurs when it flows out vigorously from the rear, A turbulent flow is generated in the area, and the flow of air flowing into the space and flowing out from the rear interferes with each other to cause annoying wind noise. It is possible to reduce wind noise by narrowing the protruding width of the eaves, but if it is too narrow, the function of the visor will be impaired. Although the eaves body was cut above the door mirror mounting portion to make it less susceptible to the influence of the door mirror, the result is that not only the expected effect is exhibited, but also the design is sacrificed and the appearance is deteriorated.

[0004]

DISCLOSURE OF THE INVENTION The present invention is a side visor for automobiles in which wind noise is reduced without impairing the design, and the construction thereof is such that the folding angle of the front inclined portion of the eaves is set to the door mirror mounting portion. Since it is gradually narrowed toward the tip, the space between the collar body and the eaves can be completely eliminated at the tip portion.

[0005]

Since the angle of the eaves body with respect to the collar body is narrow at the tip portion of the front sloped portion, it is difficult for air to flow into the space of the front sloped portion, and at that portion, air flows along the outer surface of the eaves portion. Flow, rectifies the turbulence of the air in the door mirror mounting part, and in the downstream part, the air that has flowed into the space is gradually expanded and smoothly passes, and the generation of wind noise due to resonance and air flow interference is extremely small. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automobile side visor according to the present invention will be described with reference to the drawings. As shown in FIG. 1, the side visor M for an automobile has an inverted eaves-like shape in which an inclined eaves portion 1b having a length covering up to the lower end of the side edge of the windshield is continuously formed at the tip of the horizontal eaves portion 1a. An eaves body 1 protruding obliquely downward and a brim body 2 projecting downward along the upper edge of the eaves body 1 are integrally formed of synthetic resin. The eaves body 1 opens in an inverted V shape with respect to the collar body 2, and an elongated space 3 having a triangular cross section is formed between the eaves body 1 and the collar body 2, and the space 3 is formed in the inclined eaves portion 1b. It gradually narrows toward the position where the door mirror is attached, and at the tip portion, the collar body 2 is completely closed by being integrated with the back surface of the eaves body 1,
The door mirror base mounting portion 4 is formed at the tip portion thereof (see FIG. 3). On the vehicle mounting side, which is the inner side of the collar body 2, a contact surface 5 is formed to be recessed with the upper edge slightly left, and the recessed depth corresponds to the thickness of the roof molding 6 to be mounted, The roof molding 6 is formed so as to be recessed so as to match the contact surface 5, and the roof molding 5 is covered with the eaves 1 (FIG. 4).

As shown in FIG. 4, the automobile side visor M formed in this manner is mounted in series from the rear of the roof molding 6 to the door mirror mounting portion 7, which is the lower end of the side edge of the front window, as in the conventional case. A well-known means, that is, a double-sided adhesive tape or a metal fitting, is used for mounting the automobile side visor. In the vehicle equipped with the vehicle side visor thus formed, the vehicle side visor is integrated with the vehicle, and the appearance is the same as before and gives a fearless impression.

Further, at the time of high speed running, wind noise is drastically reduced as compared with conventional automobile side visors. The reason for this has not yet been clarified accurately at this time, but air flows along the outer surface of the eaves body, and the flow rectifies the turbulence of the air near the door mirrors and the amount of air flowing into the space. It is presumed that the air pressure does not rise because the space becomes wider downstream and the air pressure does not rise, resonance does not occur when the air flows out, and there is little interference with the air flow.

Although the automobile side visor of the embodiment covers the roof mall downwardly downwardly, the rear end can be set slightly in front of it. The bending rate of the overhanging body, the inclination angle with respect to the collar body, the thickness, the width, etc. are appropriately changed according to the vehicle to be mounted, and the material is not limited to synthetic resin and may be formed of metal. Further, a cutout may be provided at the tip end portion to avoid interference with the door mirror base, or a narrow gap may be formed between the collar body and the eaves body.

[0010]

According to the present invention, the air flows along the outer surface of the eaves body, the turbulence of the air near the door mirrors is reduced, and the air is less likely to enter the space on the back side of the eaves body.
There is almost no interference between both air flows, and there is little wind noise.
